Word Origin

Old English strēon; related to Old High German gistriuni gain, Latin struere to construct

"injury caused by straining," 1550s, from strain (v.). The meaning "passage of music" (1570s) probably developed from a verbal sense of "to tighten" the voice, originally the strings of a musical instrument (late 14c.).

A group of organisms of the same species, sharing certain hereditary characteristics not typical of the entire species but minor enough not to warrant classification as a separate breed or variety. Resistance to specific antibiotics is a feature of certain strains of bacteria.

The extent to which a body is distorted when it is subjected to a deforming force, as when under stress. The distortion can involve a change both in shape and in size. All measures of strain are dimensionless (they have no unit of measure). ◇ Axial strain is equal to the ratio between the change in length of an object and its original length. ◇ Volume strain is equal to the ratio between the change in volume of an object and its original volume. It is also called bulk strain. ◇ Shear strain is equal to the ratio between the amount by which an object is skewed and its length. Compare stress. See more at Hooke's law.
